Abstract
A device for positioning the conveyor belt running through machines for thermal treatment of filaments, essentially constituted by a pressurized chamber (1) traversed by a conveyor belt (2) enclosed at each end by a sealing head mounted on a frame or movable door (3) connected to the pressurized chamber (1) by a bellows (4), each sealing head including a head of horizontal superposed rollers (5, 6) which are pressed against the opposite surfaces of the conveyor belt (2). The device includes a positioning elements (8) and a position control elements (9) acting on a very short region immediately adjacent each sealing head. The invention is more particularly applicable in the field of the textile industry, in particular of the field of treating filaments by elements of thermal treatment machines currently called heat setting machines.
